phpstudy is not accessible using a custom domain name

Question

php is installed successfully and can be accessed using 127.0.0.1 and localhost. However, when building a website, it cannot be accessed using a custom domain name. I have modified both the PHPTutorial\Apache\conf\vhost.conf and hosts files. It didn’t work. I also opened the vhost.conf file. Does anyone know what the problem is? I hope you can give me some advice. If you know anything, you can add me as Q7708720. Thank you
